Hello all,
I'm fairly new to ModBus and to communication protocols generally, so please be patient with me.
I have a production line where ModBus RTU is the communication protocol used between Omron PLC and Omron inverters. One of these inverters has a defective control board which can't be repaired.
The defective inverter is no longer available as its' production was discontinued. I tried to swap the defective inverter with another Omron inverter (other model) but there was a communication problem. I tried LS and Delta inverters too, but with no success.
After some research I found that the registers and coils addresses used for storing different variables such as the inverter status, or the run command differ from one inverter to another, for example:
Omron MX2 inverter uses address 0011h for ready signal, and Omron JX inverter uses 0010h for ready signal.
Is there any way to change the address of the ready signal and other coils and register addresses or any other solution to replace the defective inverter ??
Thank you in advance.
